ASTM A106 Gr B Carbon Steel U Type HF Welding Heat Exchanger Finned Tube
HFW Fin Tube is one of the most widely used spiral finned tubes, and are now widely used in waste heat recovery in electric power, metallurgy, cement industries, and petrochemical industries. It also called solid type fin tube,use the skin effect and proximity effect of high-frequency current to heat the outer surface of the steel strip and steel pipe while the steel strip is wound around the steel pipe until it is in a plastic state or melted and complete the welding.
This type fin tube can improving heat transfer efficiency much more than bare tube. This high-frequency welding is actually a solid-phase welding.Due to the tight welding of the fins to the base pipe / tube, these finned tubes are often used in vibrating conditions.
YUHONG Group offers ASTM A106 Gr. B HF Welding carbon steel U-Finned Tube and we sell this type of fin tubes in over 70 countries.
ASTM A106 This specification covers seamless carbon steel pipe for high-temperature service (Note 1) in NPS 1 ⁄ 8 to NPS 48 [DN 6 to DN 1200] (Note 2) inclusive, with nominal (average) wall thickness as given in ASME B36.10M. It shall be permissible to furnish pipe having other dimensions provided such pipe complies with all other requirements of this specification
